Bruce Arians just finished his fifth season as the offensive coordinator of the Pittsburgh Steelers.
While his game plans showed occasional glimpses of success, many Steelers fans have spent much of the last half decade scratching their heads and engaging in an internal debate normally centered around the question, "Why did we run that play?"
Despite mixing in some historic performances for quarterback Ben Roethlisberger and game-planning for two Super Bowls, one could easily argue that Pittsburgh's talented roster and propensity for success in other areas of the game allowed them to succeed in spite of the offensive play-calling.
Did Arians take too much heat a lot of the time? Most certainly.
However, in my opinion, many of the criticisms regarding his coaching (and, moreover, play-calling) have merit, and those who defend him rarely afford the cynics any counterargument that shows clear, statistically driven support for Arians.
Choosing to be blatant, I would offer the suggestion that his last name serve as an acronym for "A Ridiculously Inconsistent and Numb-skullish System."
That's certainly overstating the issue; in reality, I do wonder why the Steelers don't part ways with a coordinator who has largely led a talented offensive roster to mediocre league rankings during every season of his tenure.
It may be uncertain whether another coordinator could do a better job, but I'd be remiss not to mention that most coordinators being provided with such great skill talent would do two things: demand an overhaul along the offensive line and showcase comparable or better situational play-calling.
Here are some reasons that I feel Bruce Arians should not return as the offensive coordinator in the Steel City for the 2012 season.
